pure 600

turbos sound like the oscillate on light throttle under load. no boost leaks, BOV is ok and has 1/4 line.

Here is a log of the issue occurring. Started log at beginning of sound. BOV continues to make oscillation or woosh sound on constant low throttle acceleration until pedal is released. Issues began after upgrading to pure stage 2 turbos and adding 2" inlets. Issue was not present with stock turbos and 1.75" inlets, not sure if this makes a difference.

Got the stg 2 lpfp and 3.5 tmap and same turbos rebuilt lets turn it up!
